SPECIFICATION formingpart of Letters Patent No. 733,154, dated July 7, 1903.

Application filed April 20, 1903.

To @ZZ whom t may concern,.-

Be it known that I, WILLIAM S. CLAEKsoN, a citizen of the United States, and a resident of Livingston, in the county of Park and State of Montana, have invented a new and Improved Steam -Nozzle for Locomotive and other Smoke-Boxes, of which the following is a full, clear, and exact description. i

This invention relates to steam-nozzles; and it consists, substantially,in the improvements hereinafter described, and pointed out in the claims.

Though applicable to other similar purposes, my improvements are intended more especially for use in connection with the smoke-boxes of locomotives for the purpose of utilizing the exhaust-steam from the engine to promote or increase the draft upwardly through the smoke-stack.

The principal object of the invention is to overcome numerous disadvantages and obj jections common to many other devices hitherto devised for a similar purpose and to provide a steam-nozzle for the purpose specified which is both effective and reliable in operation, besides being simple in construction, comparatively inexpensive to manufacture, and also possessing the capacity for long and repeated service.

A still further object of the invention is to provide a device or nozzle of this kind which is readily adapted to proper position within a locomotive or other smoke-box, besides being strong and durable and not liable to get out of order and also being easily detached and removed for any purpose desired and not apt to become clogged up in use.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a longitudinal sectional view of a locomotive-boiler, (broken off at one end,) showing my improvements as mounted in position within the smoke-box thereof in line with the chimney or smoke-stack. Fig. 2 is an enlarged top plan view of the nozzle, showing more clearly the construction and organization of the series of steam conduits or tubes Serial No. 153,452. (No model.)

and the intermediate channels for gases therebetween; and Fig. 3 is an enlarged vertical sectional vieW of the device, taken on the line :cx of Fig. 2 and illustrating the operation thereof more clearly.

Preliminarily to amore detailed description it may be stated that in the embodiment of my improvements herein shown I preferably mount the device or nozzle in position upon the upper end of a vertically-extending conduit or pipe, the latter adapted to receive the exhaust-steam from the engine and being disposed in line with the smoke-stack before the spaces between the boiler-tubes, and the said device or nozzle is of special construction, whereby the steam passing thereto is di vided into a plurality of jets or columns moving upwardly in the line of draft through the stack and also whereby induced currents of gases are formed Within the smoke-box and caused to mingle With such jets or columns in the manner and for the purpose hereinafter more fully explained. While I have herein represented a certain preferred embodiment of my improvements,`however,it will be understood that I do not limit myself to the precise details thereof in practice, since immaterial changes therein may be resorted to coming within'the scope of my invention.

Specific reference being had to the drawings by the designating characters thereon, l represents an ordinary locomotive or other boiler, 2 the smoke-box thereof, and 3 the chimney or stack, leading upwardly from the smoke-box. At the front of the smoke-box a door 4 may or may not be provided, as desired, and located within said box is a conduit or pipe 5, adapted to be connected at its lower end in any suitable manner With the exhaust-outlet (not shown) from-the engine, said conduit being preferably circular in horizontal section, .though the same may be of other forms, and standing uprightly in advance of the spaces 6 between the tubes 7 of the said boiler.

My improved device or nozzle is designated in entirety at S and consists practically of a circular disk or plate 9, the general upper surface of which is indicated at 10, (see dotted lines, Fig. 3,) and said disk or plate is pref- ICQ erably formed with a iiange 11, seated on an inner annular ledge or shoulder 12, formed a suitable distance from the upper end of the conduit or pipe 5, the disk or plate itself being seated for a considerable distance from its edge upon the end of said vconduit or pipe, the outer surfaces of the plate and conduit being practically flush with each other. (See Fig. 3.) Suitable screw-bolts 13 or other means may be employed to retain the device or nozzle securely in place, and the said disk or plate is formed at or near the edge thereof with a series of annularly or circularly disposed slots or openings 14, the sides of each of which, as shown, are preferably substantially rectangular, but which may be round in shape, and leading upwardly from the disk or plate is a series of conduits or tubes 15, corresponding to said openings and the opposite walls 16 of each of which are radially disposed relatively to the vertical axis of the plate and also convergent upwardly, as shown, (see Fig. 2,) and the inner and outer walls 17 and 18, respectively, of each of saidconduits are also preferably convergent upwardly, the inner surface of the iiange 11 constituting a downward continuation of the corresponding surfaces of the said outer walls 18, also as shown in Fig. 3.

Pendent from the under side of the disk or plate 9 is an inverted conical spreader 19 for the ascending exhaust-steam within the conduit or pipe 5, the said spreader being hollow at 2O and the tapered walls thereof constituting practically a downward continuation of the saidinner walls 17 of the conduits or tubes 15. Instead of thus constructing these latter elements, however, I may form the same round in horizontal section,with the walls thereof substantially straight or vertical, as is apparent, and 'it will be noted that the said conduits are so organized or distributed as to form between or intermediate the same a series of radially-disposed channels 21, leading from the outer faces of the walls 18 to the edge of the hollow conical spreader 19, the sides of said channels being constituted of the adjacent side walls 16 of the successive conduits or tubes 15, as shown.

From the foregoing it will be seen that the exhaust-steam passing upwardly through the conduit or pipe 5 will be deected or spread laterally in such manner as to be directed upwardly into the series of annular conduits or tubes 15, through which said steam passes in vertically-movable jets or columns, as already mentioned, said jets or columns practically uniting as they emerge from the upper ends of said conduits 15 in the formation of a ring, which rises upwardly and through the stack in a manner to urge or greatly increase the draft, as is apparent. The said rising jets or columns of steam cause induced currents of gases within the smoke-box to pass inwardly through the radial channels 21 '2 aast to the center of the ring formed by the steani, and thus will the greater eectiveness of the device or nozzle be seen. I amthus also enabled to use a conduit or pipe 5 having large area and also a smoke stack with much larger area than hitherto, allowing greater volume of gases to be discharged without increasing the force of blast. In virtue of the conical spreader being hollow a constant eddy of the gases is maintained, which also greatly facilitates the operation of the device. Other advantages of the device will appear without further explanation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A steam-nozzle for smoke-boxes, comprising a disk or plate constructed with a series of openings having conduits or tubes closed all around and forming fixed orpermanent continuations of the sides thereof.
